Call your local pick & pull places. I had mine go out, and got one with like 60k miles on it (mine had 260k
) for like $50. Looks new, works like new.
They probably won't sell you the master cylinder, but I had no problem getting the booster. Way cheaper than I could find a new one, and I wouldn't trust a reman further than I could throw it (I have bad luck with remans, so used is prefered to reman for me).
